TANNING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 571,678, dated November 17, 1896.

Application filed December 16,1895. Serial NoIl 572,337. (No model.)

3e it known that I, ABRAHAM A. Mvnns, of Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Tanning Machinery; andv l do hereby declare the i'ollowing to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of t-his specitication.

This invention has reference to tanning machinery, and relates more especially to a mechanism of improved form for actuating tan-vat agitators.

The object ot the invention is to provide a mechanism ot' improved and simple form for actuating the agitators of a series of vats or for actuating one or more of the series to the exclusion of the others.

'The invention consists in the novel features of construction hereinafter fully described and claimed, and illustrated by the accompanying drawings, in which- Figure lis a perspective view, shown partly in, section, of my improved mechanism. Fig. 2 is an elevation of Ithe same, showing the actuating-rods detached from the agitators. Fig. 3 is an inverted plan view of a portion ot the mechanism. Fig. 4 illustrates in-elevation the connection between the reciprocating bar and the operating-levers. Fig. 5 is a detail view of the hinged joint in the operating-rod. Fig. G is a face view of one of the hangers. Fig. 7 illustrates an eccentric which maybe used on the power-shaft for driving bar I.

Any desired number of Vats A may be arranged inline, each vat having the op positelyhinged agitators B at its bottom, the free ends of the agitators being connected to the vertical rods C, which in turn are connected by hinges D to the depending rods E. Motion is imparted through reds l, and the hinges D have their pivotal pins E' headed at one end and plain at the other, as shown in Fig. 5, so that the said pins may be withdrawn and the rods G and E disconnected when the agitators are not to be operated. In such case rods E are turned upward and secured to the depending hangers F.

G represents the hides in the vat supported upon the cross-poles ll.

Depending from the ceiling of the vat-room are hangers H', and movable longitudinally therethrough is the rod Vor bar l, connected at one end by pitman J to crank J' of a powersha-ft. Bell-crank levers l are 'fulcrumed at their angles between depending double brackets L, and the upper arm of each lever is secured to the upper end of rod E, while the lower end of each lever is connected by means of link M to the slid-able bar i. The end of the link is formed with an opcnin g and the bar carries a stud over which the said link is slipped and there secured by a lockingpin M, as shown. As the bell-cranks for actuating t-he agitators of each vat have opposite position, it will be seen that one agitator will ,be raised while the other is being lowered,

and vice versa.

As many vats may be arranged in line as required, and any number of parallel lines may be actuated by bars extended from the power-shaft. By arranging the mechanism as here shown it will be seen that some of the vats in the line may be operated while the mechanism for the other vats is disconnected for the purpose of handling or otherwise treating the hides.

An eccentric N, Fig. '7, maybe used on the power-shaft instead of the mechanism shown in dotted lines, Fig. l, the bar I and link J being actuated thereby through the medium ot' strap O.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

l. The combination of the reciprocating power-bar, the depending brackets, the bellcrank levers fulcrumed at their angles to the brackets in a plane above the plane of the reciprocating bar, the links pivotally connecting the lower arms ot the levers with the said bar, the agitator mechanism, and the depending rods from the upper arms of the bellcrank levers which have detachably hinged connections with the said agitator mechanism, and the devices for supporting IOO f the said rods when not in use, substantially 'tator mechanism, and lthe device forsupportas shown and described. in?,` the said rods when not in use, substan- 2.
